Possible Heat Wave May Start This Week.

Those of you on vacation this week (like me) can expect a sunny, hot start to the week.

According to WHDH meteorologist Chris Lambert, another heat wave (at least three straight days in the 90s) is possible.

"We'll have the heat and humidity with temps running around 90, if not in the lower 90s and dew points around 70," he said on his blog. "An isolated storm threat is there in the afternoon Wednesday and Thursday, but much of the time is dry with hazy sun." 

Lamber said residents can expect 90s the entire workweek.

Here is the forecast for the start of the week:

Monday: Sunny, warm and sticky. Highs near 90!

Tuesday: Sunny, hot & humid with temps in the low 90s.

Wednesday: Sun & clouds. Hot & humid with temps near 90. Isolated storm in the afternoon.
